You have that window into your oven that allows you to watch as you cook. But it serves no purpose if it’s so greasy and cloudy you can view anything. Clean that glass with a solution made from a half lemon’s juice, a few drops of dish soap, and a tablespoon of baking soda. Make this into a loose scrub. Next, dip a damp sponge into this mixture and rub all over the glass on the door. Let this sit for about 15 minutes, then wipe off with a clean, damp cloth. The lemon’s citric acid will have cut through the grease while the baking soda and the soap lifted away the grime. The glass should sparkle!
